Rajinder Pal is a Professor in the Department of Chemical Engineering at the University of Waterloo, as well as a fellow of the Chemical Institute of Canada.
His research areas of interest lie in the rheology of dispersions, the flow of dispersions in pipelines and other process equipment, understanding the stability and demulsification of oil and water emulsions, studying column flotation, and measuring the flow of multi-phase fluids. The research area of stability and demulsification of crude oil emulsions is significant, as a large portion of the world’s crude oil is produced in the form of a water-in-oil emulsion. Professor Pal is working on novel methods for breaking the water-in-oil emulsions and is also continuing his research work on the separation of emulsified oil droplets from oily waste waters using a flotation column.
In addition to his research work, Professor Pal wrote three books and more than 150 refereed journal publications pertaining to his research areas of specialization. From 1992 to 2004, he served as Associate Editor of the Canadian Journal of Chemical Engineering.
In recognition of Professor Pal’s distinguished contributions in chemical engineering before the age of 40, he received the Syncrude Canada Innovation Award in 1998 from the Canadian Society for Chemical Engineering. He also received the Teaching Excellence Award from the UWaterloo Faculty of Engineering twice (2001 and 2017), as well as the Outstanding Performance Award from UWaterloo in 2009. In 2020, he received the prestigious Distinguished Teacher Award from the University of Waterloo.
